Problems solved by technology

Different services have different transmission delay requirements. If we continue to use the traditional beam-hopping resource allocation algorithm and pursue the maximum system capacity for users in each time slot, then real-time services require high transmission delay due to the small number of requests, and packet loss will occur. Second, due to the high tolerance of non-real-time services to transmission delay, services can be stored for

Abstract

The invention discloses a hopping beam resource allocation method taking a user service weight gain as a target function. The method comprises the following steps: calculating the service volume and time delay tolerance of each cell at the current time slot; establishing an optimization problem based on a decision problem with maximization of the deviation by taking the maximum total deviation of all attributes to the decision scheme as a target; solving the optimization problem, and determining an optimal attribute pair decision scheme; and performing resource allocation on each cell according to the optimal attribute decision scheme, and completing hopping beam resource allocation taking the user service weight gain as a target function. The method can meet real-time business service requirements and improve the overall throughput of the system.

Description

technical field [0001] The invention belongs to the field of beam-hopping satellite systems, and relates to a beam-hopping resource allocation method with user service weight gain as an objective function. Background technique [0002] With the development of broadband satellite communications, the demand for large capacity, high speed, and wide coverage has increased significantly. Most of the current wide satellite systems use multi-spot beams to increase system capacity. This system uses a fixed method to allocate resources. The power and frequency resources allocated to each beam are fixed, accounting for only a small part of the total on-board resources. Due to the diversity of service types, spatial inhomogeneity and time-varying service distribution, the way of fixed allocation of resources cannot meet the requirements of efficient transmission and on-demand coverage, resulting in waste of communication resources. [0003] In order to effectively use the resources on...
